  3. FeedbackVaillant say a dripping external flue is normal !
  4. Detail– I am surprised to discover Vaillant say it is acceptable to expect my 5 month old Vaillant ecotec plus 424 boiler to drip from the external flue,…and in my case, to the extent, it appears, to have produced a damp patch in my concrete driveway (favourable for green algae to grow) . I am also disappointed to learn that the additional flimsy plastic waste pipe suspended under the boiler , apart from taking up valuable room and poorly protected from being bumped into or knocked, which passes out through the gable wall does not appear to remove this condensate to the drain . I was told the flue drip was produced as a result of the weather conditions !
    Am I to expect icicles at Xmas ?
    I have been advised that the boiler is covered by the warranty but the installation of the flue is not , therefore a callout charge would be applied by your installer re the flue, but in my case I have been advised by Vaillant this dripping is normal and my fitter says there is nothing wrong with it!
    I would not have bought this type of boiler had I known it was prone to this kind of nuisance and fragility with re to the additional suspended condensate waste pipe .

  • Detail– Since we turned the heating back on at the music school in September and nothing happened we’ve been getting colder by the day! Thanks to the new Vaillant boiler we’re now warmer than we’ve ever been before. Many Thanks


  1. What is a Combi boiler?

A Combi boiler heats water as you draw it from the tap. It doesn’t need a water storage tank or a cylinder because the boiler’s connected directly to the water mains, heating water as it’s needed. 

2.How do I top up water pressure?

Combi and system boilers and your heating system work under pressure. If the pressure drops below a certain level the boiler will not fire (start).

Combi and system boilers need a minimum pressure within the system to work. Leaks in the system will cause your boiler to lose pressure. Leaks can be very small and you may not be able to see them. It is easy to solve this loss in pressure by topping up your system – your installer will be able to do this quickly. However, it is essential they also find and fix the leak.

It is a good idea to regularly check the pressure gauge to make sure there are no tiny leaks within your system – ask your installer
to show you how if you’re not sure. You can find the correct pressure levels for your boiler and instructions for repressurizing the
system in the user instructions. If you are in any doubt, we recommend you ask a competent person, such as an installer,
to repressurise your system for you.

3.Why should I have weather compensation?

Weather compensation control is an optional control available for modern boilers. It works by monitoring the temperature outside and using this information to help the boiler work as efficiently as possible.

Weather compensation control is worth adding to a modern central-heating system as it works out when the boiler needs to operate. You simply tell the system what time you want the house to be warm and the controls take care of this in the most efficient way possible. Controls like this can also save you more on your energy bills.
